讨论了应用高频电感耦合等离子体(ICP)消解氟里昂类废弃物的可行性及与国际先进技术的比较;应用低功率ICP系统进行氟里昂12的模拟消解,用GC-ECD方法对尾气中的残余成分和浓度进行分析,证明该系统对氟里昂12的处理效率高于99.9%,可以发展成为未来环保废物处理领域的一项新技术。

An inductively coupled plasma (ICP) system used for the destruction of Freon wastes has been discussed and compared with the advanced foreign technology used for the destruction of hazardous wastes. The advantages of the ICP technology and its possibility to be developed into a practical environmental protection technology are also discussed. The exhaust gas from the ICP system is sampled and analyzed by GC-ECD method. Phosgene and trace amounts of CF~2Cl~2, CHCl~3, CH~2Cl~2, CCl~4 etc. are identified quantitatively. The total destruction efficiency of the ICP system for Freon 12 is calculated to be more than 99.9%.
